HAND FENCE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 508,836, dated November14, 1893.

Application filed June 30, 1893.

citizen of the United States, residing at Ryan, -1n the county of Bushand State of Kansas,

have invented anew and useful Hand Fence- Maehine, of which thefollowing is a specifi-' This invention relates to hand fence machines;and it has for its object to provide certain improvements in handoperated devices for twisting the strands of wires about each picket,during the operation of constructing a wire-picket fence.

To this end the main and primary object of the present invention is tosimplify the construction of hand fence machines, while at the same timeproviding for an efficient operation thereof, whereby a full twist ofthe wires is secured.-

With these and other objects in View which will readily appear as thenature of the invention is better understood, the same consists in thenovel construction, combination and arrangement of parts hereinaftermore fully described, illustrated and claimed.

In the accompanying drawings:Figure l V is a perspective View of aportion of a picket fence, showingmy improved hand fence machineconnected with the stretched wires. Fig. 2 is an enlarged detailperspective view of one of the shuttle arms and a swinging shuttle barat the extremity of such arm.

Referring to the accompanying'drawings, A represents a section of apicket fence, during construction, in which are arranged thelongitudinal fence wires a, between which are adapted to be inserted thepickets, and which are adapted to be twisted at each side of eachsucceeding picket in order to construct a line of fencing.

In order to twist the pairs of fence wires a, at each side of thepicket, I employ the hand fence machine B, constructed in accordancewith this invention and provided with the main upright hand bar 0. Theupright hand bar 0, is preferably tubular in cross section and isadapted to adjustably receive the innor loop clamps D, formed at theinner ends of the stationary shuttle arms E. The shuttle arms E, arearranged in a number to correspond to the number of pairs of wires em-Serial No.4'79,308- (No model.)

ployed in constructing the line of fencing, and said shuttle arms E, arefurther provided at their loop ends with the perforations F, adapted toreceive the elampin g bolts G, which clamping bolts, when tightened,bind' the loop clamps D, securely on the hand bar 0,

so that the stationary shuttle armsare carried up and down and forwardand backward, to-.

By thus clamping" stationary shuttle arms E, are the swinging I shuttlebars H. The swinging shuttle bars H, are provided in their under edgeswith a series of wire notches I, in whichare adapted to be inserted thewires c, of the fence, so that such wires will be constantly heldapartfrom each other to provide for the insertion of the picketsthere-between, while at the same time, by the movement of the machine,the wires of each pair are twisted upon each other. By having a numberof wire notches in the edges of the shuttle arms, the wires a, can beheld as near to or as far apart from each other as may be necessary,according to the width of picket employed. The fence wires are securelylocked in the wire notches of the shuttle-bars by means of the springlocking arms J. The spring locking arms J, are pivoted at K, to theouter ends of the'shuttle bars and are provided at their other free endswith the catch points L that are adapted to be sprung into engagementwith the catch openings M, formed in the shuttle bars near their pivots.After the insertion of the pairs of fence wires in each shuttle bar ofthe machine, the locking arms are swung under the fence wires and sprunginto engagementwith the catch openings of the shuttle bars, therebyproviding means for securely locking the wires in the bars toefiectually prevent the same from being displaced when'being.

twisted. I

From the foregoing, it is thought that the operation and construction ofthe heroin described hand operated fence machine will be readilyapparent tothoseskilled-in the art.

It is simply necessary to arrange and lock the fence wires in theshuttle bars of the machine in the manner just described, and then bygrasping the hand bar 0, and shoving the same forward and down andpulling it from the fence and up, the pairs of fence wires will becompletely twisted at one side of each succeeding picket after theinsertion thereof between the wires.

It will be apparent that slight modifications of the machine hereindescribed may be employed without altering the principles of theinvention in any particular, such for instance as employing any numberof shuttle arms and bars, for it 1n ust be obvious that the number ofshuttle arms and bars depends upon the height of fence and number ofline wires used in such fence, and it has been found advisable to employa shuttle arm and bar to every six inches in height of a fence. Havingthus described the invention, what is claimed, and desired to be securedby Letters Patent, is

1. In a hand fence machine, an upright hand bar, a series of stationaryshuttle arms adjustably clamped at one end to said hand bar, swingingshuttle bars pivoted at one end 'to said shuttle arms and provided witha se:

ries of wire notches in one edge, and means for locking the wires in thewire notches of said bars,substantially as set forth.

2. In a hand fence machine, the combination of an upright hand bar,aseries of shuttle arms having loop clamps at one end adjustablyembracing the hand bar, swinging shuttle bars pivoted at one end to theouter extremities of said shuttle arms and provided at one edge with aseries of wire notches and each having a single catch opening, andspring locking arms pivoted atone end to each shuttle bar and having attheir other ends catch points adapted to be sprung into engagement withsaid catch openings, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
